CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of Chinese Patent ApplicationNo. 201810748446.0 filed on Jun. 29, 2018. The contents of the above arehereby incorporated by reference.

FIELD OF THE INVENTION

The present invention relates generally to fashion design, and moreparticularly, to a system for designing brassiere based on virtualreality technology.

BACKGROUND OF THE INVENTION

Statistics showed that 80% of women of developed countries in Europe andAmerica wore incorrectly sized brassiere. Similarly, this phenomenonalso applied in developing countries, so made-to-measure brassiere maysolve this problem.

Women always expect to wear correctly sized and charming brassieredesigned by themselves on any occasion. However, it is difficult for awoman to communicate her ideas and thoughts with the designer. In themean time, women are usually not familiar with how to design abrassiere.

But now, basing on virtual reality technology, it is possible to designan expected personalized brassiere by experiencing immersion into asimulation environment of three dimensional dynamic vision with physicalinteraction with objects, in which the user can select wearing scene andmatch clothing by applying a brassiere design application program andusing a smart mobile terminal.

However, as a bra cup is vital to fitness of a brassiere, physicalobjects are still required for simulating wearing effect of thebrassiere, so as to guide the design of the brassiere.
